Most of the soft tissue calcifications within the head and neck region might not be accompanied by clinical symptoms but may indicate some pathological conditions.
The aim of this research was to determine the prevalence of soft tissue calcifications in cone beam computed tomography (CBCT) images of mandibular region.
In this cross sectional study the CBCT images of 602 patients including 294 men and 308 women with mean age 41.38±15.18 years were evaluated regarding the presence, anatomical location; type (single or multiple) and size of soft tissue calcification in mandibular region. All CBCT images were acquired by NewTom VGi scanner. Odds ratio and chi-square tests were used for data analysis and < 0.05 was considered to be statistically significant.
156 out of 602 patients had at least one soft tissue calcification in their mandibular region (25.9%. of studied population with mean age 51.7±18.03 years). Men showed significantly higher rate of soft tissue calcification than women (30.3% vs. 21.8%). Soft tissue calcification was predominantly seen at posterior region of the mandible (88%) and most of them were single (60.7%). The prevalence of soft tissue calcification increased with age. Most of the detected soft tissue calcifications were smaller than 3mm (90%).
Soft tissue calcifications in mandibular area were a relatively common finding especially in posterior region and more likely to happen in men and in older age group.
头颈部区域的大多数软组织钙化可能没有临床症状，但可能提示一些病理状况。
本研究的目的是确定下颌区域锥形束计算机断层扫描（CBCT）图像中软组织钙化的患病率。
在这项横断面研究中，对602例患者的CBCT图像进行了评估，其中包括294名男性和308名女性，平均年龄为41.38±15.18岁，评估内容包括下颌区域软组织钙化的存在情况、解剖位置、类型（单发或多发）和大小。所有CBCT图像均由NewTom VGi扫描仪采集。采用优势比和卡方检验进行数据分析，P<0.05被认为具有统计学意义。
602例患者中有156例在下颌区域至少有一处软组织钙化（占研究人群的25.9%，平均年龄为51.7±18.03岁）。男性软组织钙化率显著高于女性（30.3%对21.8%）。软组织钙化主要见于下颌骨后部（88%），且大多数为单发（60.7%）。软组织钙化的患病率随年龄增长而增加。大多数检测到的软组织钙化小于3mm（90%）。
下颌区域的软组织钙化是一个相对常见的发现，尤其是在后部区域，并且更有可能发生在男性和老年人群中。
